Products Description
We professionally manufacture a full range of Sch10, Sch20, Sch40, Sch60, Sch80 heavy-wall seamless steel pipes, strictly complying with authoritative international and domestic standards including ASME/ANSI B36.10, API 5L and GB/T 8163. As core pressure-bearing pipes for industrial pipeline systems, SCH (Schedule) represents the pipe wall thickness grade. The higher the SCH number, the thicker the pipe wall, and the stronger the pressure resistance and structural stability. Our products accurately meet industrial requirements of different pressure, temperature and medium working conditions.
Features & Applications of Each SCH Grade
♦ ♦ ♦ Sch10 Heavy-wall Seamless Pipe
A light-duty thick-wall pipe with light weight and high cost performance and moderate pressure resistance. It is mainly used for low-pressure and normal-temperature fluid transmission, including building water supply and drainage, general ventilation pipelines, low-pressure heating and ventilation, and light industrial pipelines with convenient installation and low cost.
♦ ♦ ♦ Sch20 Heavy-wall Seamless Pipe
With better wall thickness and pressure resistance than Sch10, it balances economy and practicality. It is widely applied in municipal engineering pipelines, general chemical fluid transmission, low-pressure oil and gas transmission, and mechanical equipment auxiliary pipelines, serving as a common pipe for civil and general industrial scenarios.
♦ ♦ ♦ Sch40 Heavy-wall Seamless Pipe (Standard STD)
The most widely used standard wall thickness grade in the industry with balanced wall thickness, strength and pressure resistance. It adapts to most medium-pressure and normal-temperature industrial working conditions, covering petrochemical, power and thermal engineering, water treatment, metallurgy and general equipment pressure pipelines, featuring strong universality and adaptability.
♦ ♦ ♦ Sch60 Heavy-wall Seamless Pipe
Adopting reinforced wall thickness design, it has greatly improved pressure resistance, impact resistance and deformation resistance, suitable for medium-high pressure working conditions with slight temperature difference. It is mainly used for medium-sized chemical devices, high-pressure water treatment, thermal pipe networks, mine fluid transmission and industrial high-pressure auxiliary pipelines with higher strength requirements.
♦ ♦ ♦ Sch80 Heavy-wall Seamless Pipe (Extra Strong XS)
A high-strength reinforced pipe with the thickest wall and highest structural strength in the series. It features excellent high pressure resistance, high temperature resistance, corrosion resistance and fatigue resistance, capable of long-term operation under harsh working conditions with high pressure, high temperature and corrosive media. It is widely used in core fields such as petroleum refining, high-pressure oil and gas transmission, power stations, heavy chemical industry, pressure vessel supporting and high-end industrial pressure-bearing pipelines with superior safety and stability.
